when I start my truck up it run great, but after driving it about 30 minute it start to missing like it not getting the gas. I need to know what can I do to fix it, please someone help.
Oh and I cant fine the fuel filter.

I'll looked all under that truck and I can fine the filter no place. Tell u what I did fine was another fuel pump and a fuel reserve tank but no fuel filter oh and there is a fuel pump in the gas tank.

On an '86 and ONLY an '86 EFI (well.. '85 2.3EFI's have it too)
the filter is inside the black cannister. ( Not sure if this applies .)

and

i got an 86 bronco ii 2.9 auto 4x4 and i just replaced mine, the filter is in the black canister, use an oil filter wrench to unscrew if on tight, mine was just hand tight. on my truck it was located about 6 inches behind the transfer case skid plate. Be careful not too over tighten it or you'll bust that cheap little o-ring that seals it up.
